To (ZZZ who-m may concern:

Be it known that i FREDERICK BERNAU, a citizen of the United ,States, re-

siding at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in I Automatic 'Nonprinting Mechanism, of

= which the following is a specification.

This invention relates to means for effecting splits in adding, subtracting, or listing machines having printing mechanism. t

ulVhile the, present invention may be used in connection with any adding, subtracting or listing machine having printing means,- and a traveling carriage, it is particularly, adapted for use with the? Ellis -mach1ne,

and reference may be had to the patents granted to Halcolm Ellis, morev pa' ticutrol by"theposition of the traveling carriage. The mechanism which effects the of one or more adjustable stops onthe'car-v split or theblocking of certain ones, or all,- ofthe typejse'ctors, is under the control riage, whereby 'th'e'desired number of type sectors may be: blocked according -to the number and position of thestops which, in turn, determines the eflect of the split in the different columns according to the nature ofthe work being carried on.

According to-the nature of the work, theblocking mechanism for the type sectors may comprise a bail or bar adapted-to block all of the. type sectors, or, atbail which is cut out .or provided with effective and noneffective parts so that certain of the type sectors will be blocked while others will be fr'eeto print, or, the bail maybe multiple, with its different parts subject to independent control by independent 'stopsion the carriage.

By use of my invention it is possible to determine what is commonly known 'as. an

' render it effective.

thescope of the invention.

In the accompanying drawings: Figure 1 1s a plan view showing one form of the mechanism, together with a part of' the'rack stop bar of'the carriage, and a stop, relatively arranged to render the mechani'sm'operative. I

bailsf each having its own point or stop, are employed.

Fig. 6 is a side elevation of the mechanism of Fig. 5.

Fig 7 is a detail plan view showing by full and dotted lines, different forms of pears-at P Figs. 3 and-4. In Fig- 5 the Y dotted lines P represent thegroup of nine printing arms which represent nine numerical orders, it being understood that any number of printing arms, corresponding to the rows or banks of keys of the machine, are employed. Arms 1?, ne for each printing sector, set the printing sectors P according to the previous setting of the keyboard, when the machine is operated, as explained in Ellis Patent No. 1,197 ,27 6, for instance.

The arms P are provided with fingers a to enable them to be held back, locked or blocked by the mechanism of the present invention.

The rack bar C is carried by the travel ing carriage as in the Ellis Patent 1,197,276 and serves to carry any desired number of removable'or adjustable stops of whichone is shown at 1 in Figs. 1, 3, 4, and appears in a slightly modified form, 1, in Fig. '7. It will be understood that while only one stopis illustrated, the bar C may be pro- .vided with as many stops as desired, each being settable to any desired position there on, to carry outthe purposes of the present invention. The stop 1, whose tip 1 is provided with a double bevel on its lower face as shown inrFig. 2, is for the purpose of rendering the split mechanism effective when the carriage isin such position that said tip 1" will engage the appropriate part of the split mechanism. I

Referring first to Figs. 1, 3 and 4, arms 2 are secured at 3 to the plates P for the purpose of supporting the split mechanism in proper relationship to the group of print ing arms Pf Suitably pivoted to the arms 2 at 4 is a bail comprising arms 5 and a locking bar 6.

A contractile coil spring 7 connected to 1, due to the carriage having assumed the desired position for effecting a nonprinting condition of any or all of the arms P according to the form of the bar 6, the bail is depressed, bringing the bar 6 into engagement with the fingers (1. Consequently as long as the carriage remains in that position so many of the arms P will be latched or blocked in the manner shown in Fig. 4 as will correspond to the efiective part of the bar 6. If that bar has straight lower edge, as shown by full lines in Figure 1, all of the printing arms P will be latched. it, however, the bar 6 is provided with a cut out portion, as shown at 6, Figure 8, certain of the arms P will be latched and others will be free. Either form of the bar 6 may be employed. If the cut out form he used,'the arms P which are opposite the cut out part 6 will print when the machine is put through its cycle of operation and the remaining arms P to the right of those which are printing will not operate, thereby cutting off orsplitting ciphers from the rightof the numbcnprinted.

In Figures 5 and 6 there form of the invention where the bail is made in two parts, each being adapted for con? trol independently of the other according to the use of an additional stop 1 and its position on the rack stock bar G The mechanism is supported from plates P by arms whichcarry at their upper ends the screws 4. By reason of two bailsor latching mechanisms being employed, it is preferable to brace the arms 2 by the provision of a yoke 10. Pivotally mounted on the blank portions of the screws 4 are the is illustrated a i independent bails 11, 12, the'former being longer than the latter, and, if desired, braced against flexing by a supplemental L- shaped piece 13. The bail 11 carries an offset point 14 corresponding to the point 5, 5 The bail 12 carries a point 15 of similar form. The respective bails 11, 12, are re-' 3 acetate ment of independent stops corresponding to stops 1 on the bar C of the carriagaone or the? other, or both, or neither of said bails will be tiperated. This form of the mocha -My invention may be put to many uses and I only give certain examples of the work of the embodiments hereinbefore described.

The following examples illustrate how the stops may be set on'the carriage, and

the carriage positioned, to effect cooperation between the stops'and cut-out bars or bails.

in any desired manner;

. marginal bar isprinted (but 11'otjadded) by the use of 'ploycd that folio number.

Referring to the embodiment of the invention shown in Figs. 1, 9., 3, 4, and with the barcut out as shown at 6 a split maybe effected according to the following e'X- 'amples:

Example A 4 Amount Emample B Example A is accomplishedas follows: it cut out bail (i as shown in'Fig. 8, is emwill be effective only on the first and second sectors P, Fig. :5 beginning at the right side. Itis understood, however, that the stop"-1, Fi'g. l is arranged on the C to depress the bail 6*- as shown in Fig. at, prior to the entering of the .set up on thekeyboard in those orders-to the left of the 1st and 2nd orders and the machine is then operated. "The number 1,245

other mechanisms explained in an earlier Ellis patent namely, No. -1,197,276, dated September 5, 1916. 'kt' tnecom'pletion of printing the folio numbenthe carriage automatically tabulates ormoves to the amount column whereupon the amount of 76.98 is then set up on the keyboard in the ordinary manner and the machine is thereafter op-' orated. The'amount of 76.98 is printed and added in either one orboth of the two aci-iimulators provided therefor.

The accumulator used for this addition is determined by the selection of a stop that is The folio number 1,245 is placed on the bar C opposite the column that is provided in which the amount is printed (the ahovest p being more fully explained. earlier Ellis patents). This operation is coi'itinued until a total of the various-amounts is to be taken which. is usually done at the bottom of the same column where the amounts are printed. However, the operation of taking a total need. not be limited to this one column as this operation can be'performed in any position on the printing surface, although it is not desirable to print this total in the same column that is provided forthe folio number. p Example B can be accomplished in somewhat the same manner as Examplefit.

trict "No. The other is set to permit the printing to take place in the column arranged for the Bank No. The general operations are very much the same as those required .for'ExampleA except there are two folio numbers instead of one; therefore, three operations of the machine are required. For instance, number 12 is set up on the keyboard and the machine is'operat'ed. After the printing has taken place the carriage automatically tabulates to the Bank column where the 450 is setup on the keyboard and the machine is operated. The-450 is printed and the carriage again tabulates to the Amount column where the amount is setup and is printed and added.

The mechanism shown in Figs. 5 and 6- may be used' for splitting so that items in two adjoining columns can be accumulated on asingle accumulator, for instance the Dr. accumulator of the machine,with the ciphers at the right omitted; and another column may be accumulated on another accumulator, as, for instance, the Cr. ac

. Net

In the above Example 0 the item. 1,324, is set up on the keyboard and printed and added,the remaining orders of type izo - taken instead of a total because the taking ing arms to operate.

of a total would clear the Dr. accumulator and as items representing Pieces have been accumulated in the righthand section of that accumulator, it is, obviously not desired to eliminate them, but, on the other hand to retain them in the accumulator. The bail '12 looks the arms P which represents the items in the Pieces column and hence when the sub-total of the items in the Yds column is printed, no printing occurs in the Pieces column] Having taken the sub-total representing the items in the Yds. colun1n,the carriage is moved to take the total of the items in the Pieces column. Now the bail 11 blocks all arms P related to the left hand section of the accumulator so that no printing corresponding to the Yds. column will occur.

The total of the Pieces column may then be taken. Thus, two columns may be carried in'the Dr. accumulator and another column, for instance, items under Net weight may be carried in the Cr. accumulator.

The foregoing actions are, of course, de pendent upon proper settingof the stops -1.

for engaging the points 14, 15, to render the bails 11, 12, effective when the carriage is in the predetermined column positions. i

"With the provision of a cut out bar such as shown in Fig. 8, it is possible to hold back either the entire group, or only. a predetermined number, of type sector arms P according to the form of stop used on the carriage. For instance, by the use of agiven stop on the carriage, the bail 6 will be de-- pressed only far enough tdrender effective the wider part of the bail to hold back certain type sector arms, the narrower or cut out. portion of the bail allowing the remain- (in the other hand, if a stop having a deeper point 5*, (i. e. one which extends down farther) or one which is bent down. or inclined, is used, the bail 6 will be depressed to a greater extent and the cut-out edge will engage those type sector arms which are normally free .and retain them against-movement.
